Abstract: 745,240. Automatic speed control systems. PEUGEOT ET CIE. June 29, 1953 [July 8, 1952; Jan. 5, 1953], No. 17927/53. Class 38 (4). [Also in Group XXXVII] A magnetic vibrator A intended to maintain the speed of a small motor B at a desired level and permit variation of the level comprises a magnetic bar 21 fixed to the motor housing D and supporting a core 29. The upper half of the core carries a coil 32 connected in shunt across the motor armature through a rheostat (Fig. 1, not shown) whilst the lower half carries a coil 33 in series with the armature, the motor field coils, and a pair of contacts 34, 35 carried by the bar 21. Ends 27, 28 of the core 29 respectively co-operate with magnetic lugs 25, 26 attached to a magnetic disc 24 pivotally mounted by a journal 23 in the bar 21 and hence the coils 32, 33 tend to rotate the disc in opposite directions. A spring 31 connected between the disc 24 and the bar tends to turn the disc in the direction f so that an abutment 38 on the disc engages a blade spring 37 carrying the contact 35 and holds contacts 34, 35 closed. The disc is moved in the opposite direction to open the contacts by the coil 32 against the combined opposition of the coil 33 and the spring 31. The smaller the difference between the opposed torques acting on the disc the greater is the oscillation frequency of the disc, and since this difference is reduced on a heavier load both by a heavier current in coil 33 and by a reduced voltage across the coil 32 the motor will tend to maintain its speed. Speed variation is obtained by adjusting the rheostat. A capacitor 40 on the bar 21 shunts the contacts 34, 35.

Filed: 1955-06-28
Abstract: A solid solution of a solute in a solvent, wherein the distribution coefficient of the solute is greater than unity, is produced by crystallizing from a liquid solution maintained in a saturated condition by the presence <PICT:0779509/III/1> <PICT:0779509/III/2> of excess solute in contact with the liquid.  The solvent may be a semiconductor material such as germanium, and the solute may be silicon or boron.  In one method (Fig. 1) a solid solution 3 is obtained by slowly withdrawing a container 14 of liquid solution 2 from a furnace 1.  Solid solute 4 is maintained in contact with the liquid 2 to replace solute in solution, as the solute favours the solid phase 3 and the solute in the liquid solution is depleted as the crystal is grown.  In another method (Fig. 2) a crystal 8 is grown by slow withdrawal from a melt 5, the melt being kept saturated by excess solute 7.  In both methods the temperature of the liquid solution may remain constant or may be varied.  Specification 754,767 is referred to.
